  • 摘要:

    为明晰超宽带电磁脉冲对引信的干扰和损伤影响,确定引信-电磁脉冲效应的阈值区间,针对当前引信-电磁脉冲效应数据样本少,难以准确评估引信的抗电磁脉冲能力的难题,建立了马尔可夫蒙特卡罗估计的引信-电磁脉冲效应阈值分析模型。通过构建的超宽带电磁脉冲模拟器的引信效应测试系统,对典型引信进行辐照试验,得到引信-电磁脉冲的效应规律及干扰阈值。试验结果表明:引信通信故障的效应阈值均值为28.262 kV/m,均值的95%可信区间为(27.390,29.129)kV/m;方差的后验期望估计为1.867 kV/m,方差的95%可信区间为(0.834,4.182)kV/m。所提模型可用作多种引信的电磁脉冲效应阈值估计,为提高引信的抗电磁干扰能力提供理论基础和试验手段。
